This boat fuel pump is a screw type of PD pump. On ships, it is often used to transport various liquids such as seawater, fresh water, sewage, lubricating oil and fuel oil. With the correct selection of materials and structures, it can convey lubricating or non-lubricating, clean or low-viscosity or low-viscosity containing solid particles. Various media with high viscosity, with or without corrosiveness. Shaft seals are available in various forms, with long service life, less leakage and a wide range of applications. It also has vertical and horizontal differences.
Stable conveying pressure and constant flow rate. No pulsation or stirring medium, continuous and smooth supply.
Low noise and long life
Low vibration, no direct mechanical wear, low noise and long service life.
Excellent self-priming performance. Even if the conveyed medium has a high viscosity.
Convey extremely high-viscosity chemical materials and transport medium in high temperature, corrosion, etc.
DBM has always been committed to providing customers with the best products and services, all products are sent to customers after strict quality inspection. In terms of twin-screw pump production, our company has a professional team with more than 20 years of experience in the field of technology research and development, equipped with advanced production equipment and testing equipment, as well as a complete production system and digital system.
At the same time of high-efficiency and high-quality production, it ensures that the products can meet the transportation needs of customers for various media.
This boat fuel pump is a double-suction structure of a twin-screw pump, and the spiral surface adopts an advanced Ω-shaped symmetrical form;
Through the bearing positioning, the two screws do not contact each other in the bushing, and a constant gap is maintained between the tooth sides. There is also a constant gap between the circle and the inner surface of the bushing. The transmission of the two screws is completed by synchronous gears. This structure can also transport a large amount of non-lubricating media and media of various viscosities. Since the core working parts of the screw sleeve do not touch each other, there is no danger even if it runs dry for a short time (3~5min). Therefore, it is widely used.
The pump of this structure can realize forward and reverse operation (It is a unique structure designed by our company, please request it in the contract if you need this function)
Tank farm oil delivery, backfilling, loading pump, fuel transfer pump, fuel injection pump, etc.
Shipbuilding: used as marine loading pump, scavenger pump, marine ballast pump, main engine lubricating oil pump, cargo oil pump, etc.
